' To all whom it may concern:

Be it known that I, GUsTAv TiiRK, subject of Germany, residing at Meiningen, Rohrerstrasse 16, Germany, have invented certain new and useful Improvements in a Machine for Manufacturing Fiber Strips from Paper Pulp and the like (for which I have filed applications as follows: Germany, February 12, 1918; Austria, February 18, 1918- Hungary, February 19, 1918; Finland, May 29, 1918; Denmark, November 2, 1918; Norway, November 13,1918; Holland, November 11, 1918; Switzerland, October 26, 1918; Sweden, October 31, 1918; and Belgium, December 2, 1918), of which the following is a specification.

In producin narrow strips or ribbons from paper pu p or similar fibrous material by the -aid of known machines (paper ma.- chines) it is of importance to take care that the working of the plant is a financial success, for which reason on the one hand the breadth of the machine is to be well taken advantage of, that is to say, is fully utilized up to the very edges, and on the other hand care is to be taken that the produced fleecetravels at as high a speed as possible. Particularly this high speed makes it necessary in feeding or conducting the strips to provide for a high subdivision of the fleece. Since particularly in feeding the strips to the spools or coiling devices or other gathering devices or in feeding the strips to devices or apparatus for turning them into rovings by rubbing or rounding them, great difficulty had occured on account of want of room, and the consequence is that frequently a great amount of waste occurs.

To avoid these difliculties as much as possible it has been proposed to allow the rubbing or rounding apparatus to be followed by a-number of endless felts or aprons corresponding to the number of groups of the rounding apparatus, which endless felts were arranged at suitable distances from one another. It has also been proposed to arrange the rubbing devices close-to the delivering cylinder or close to the c linder press of a paper machine and to con not the fiber strips by suitable felts or bands to the coiling or gathering means. It has also been proposed to use a delivering cylinder of special large diameter, so as to enable a great num- Specification of Letters Patent.

' ber of devices being used for leading the strips away.

In the first instance the plant would be very expensive on accountof the great number of the necessary felts or carrying bands, and in the second instance on account of the large cylinder. The present invention therefore has the object to simplify the plant and to make the manufacturing of fiber strips for the purpose of making yarn, twine, cord and the like a financial success. This ob- )BCt in view a special endless felt cloth or apron is used which follows the web paper machine or cylinder paper machine directly to conduct the fiber strips. away, and together with the cloth or band a number of conveying devices are used, which pick up the strips preferably from the underside of the endless cloth.

This endless cloth may be made of a usual felt material. It has however been found that the fiber strips will not adhere to wool felt when to a great extent deprived from its water. For this reason the invention also proposes to make the apron from fiber, which has a greater adhesive power than wool, from which heretofore such aprons were made. According to the invention therefore this apron is preferably made of vegetable or mineral fibers, such as cotton, linen, cellulose, asbestos and the like, which as is known have a greater capillarly adhesive power than sheeps wool.

In the drawing Fig. 1 is a diagrammatical side view of an apparatus by which the above described invention can be carried out.

Fig. 2 is a plan.

' In connection with the endless sieve a of a web machine an endless cloth or apron b is used, which is led about a number of guiding rolls and which is in contact with the said sieve a in such manner that the strips formed on the sieve are fed to the cloth or apron b, which conducts the strips away preferably on its under-surface. Beneath the a ron b there are a number of taking up or elivering devices, for instance a number of rubbing or roundingapparatus 0 to which the strips are conducted in. groups from the apron b. Beneath the rounding apparatus a number of gathering or coiling devices 03 are provided. If desired the rounding device a can be omitted, so as to conduct the strips from the larger surfaces of the apron b directly to the gathering devices 03.

The new machine is a great simplification over any known machines having a similar object, because in the present case only a single apron or endless cloth is used and in comparison to the known machines having a large delivering cylinder it is evident that the costs of the complete plant are considerably reduced.

I claim:

1. A machine for manufacturing fiber strips from paper pulp and the like comprising an endless sieve-band, and a feltband in contact with the endless sieve-band and adapted to pick up fiber strips carried along by the sieve-band in combination with a number of delivering devices arranged in such manner as to pick up the fiber strips from the felt-band in separate groups.

2. -A machine for manufacturing fiber strips from paper pulp and the like comprising an endless sieve-band, and a felt-band in contact with the endless sieve-band and adapted to pick up fiber strips carried along by the sieve-band and arranged to conduct the strips along'its underside, in combination with a number of delivering devices below the said felt-band and adapted to pick up the fiber strips from the under surface of the apron.

3. A machine for manufacturing fiber strips from paper pulp and the like comprising an endless sieve-band, and a felt band in contact with the endless sieve-band and adapted to pick up fiber strips carried along by the sieve-band in combination with a number of rounding devices arranged to pick up the fiber strips from the felt-band and round them in separate groups.

I 4. A machine for manufacturing fiber strips from paper pulp and the like comprising an endless sieve-band, and a felt-band in contact with the endless sieve-band and adapted to pick up fiber strips carried along by the sieve-band and arranged to conduct the strips along the underside, in combination with a number of rounding devices below the felt-band, arranged to pick up the fiber strips from the underside and round them, and with a number of gathering devices below therounding devices.
